Stereo Evaluation Module Reference Design of the Digital Input: Class-D: IV Sense Audio Amplifier
This reference design provides a high-performance stereo audio subsystem for use in PC applications. It operates off a single supply: ranging from 4.5 V to 16 V: and features the TAS2770: a digital-input Class-D audio amplifier that provides excellent noise and distortion performance and is available in both WCSP and QFN packages. The design also includes two low-dropout fixed voltage regulators: the TL760M33 and TPS73618: which generate the necessary 3.3 V and 1.8 V system rails: respectively. The reference design’s versatile digital-input interface allows for a wide variety of input formats: while providing output data for voltage and current sense: supply voltage (VBAT) and temperature. The reference design also includes multiplexing to allow multiple input sources to the digital inputs. Additionally: the TAS2770 incorporates an automatic gain controller that can track VBAT to limit the output voltage: as desired. This function can help extend the battery life of battery-powered applications: such as laptops and tablets: and prevent system-level brownout. Inter-chip limiter alignment can be configured on multiple TAS2770 devices to coordinate limiter activity using a shared digital output. This will ensure that the entire system maintains comparable gain levels at all times to provide the best listening experience.
